RAIL-B 0ND Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed May 9, 1907. Serial No. 372,814.

T 0 all whom it may concern:

Be it known that I, ROBERT OSTICK, a citizen of the United States,residing at Covington, in the county of Kenton and State .of Kentucky,have invented a new and useful Improvement in Rail-Bonds, of which thefollowing is a specification.

My invention relates to an improvement in a rail bond.

One of the objects of my invention is to provide means for frictionallyclamping a rail bond to the bottom surface of two adjoining rails,whereby the rails are locked together against lateral displacement.

Another object of my invention is to provide a pair of plates engagingthe upper inclined surface of the base of the rails, said platessupporting filling blocks, adapted to clamp a rail bond to the undersurface of the flanges of adjoining rails as the plates are clamped inposition.

Another object of my invention is to provide a pair of plates adapted tobe clamped upon each side of two adjoining rails, said plates beingprovided with inwardly projecting flanges having a curved surface forsupporting filling blocks, whereby a secure clamping of the rail bondmay be effected, irrespective of the plane the clamping plates occupy inposition.

The features of my invention are more fully set forth in the descriptionof the accompanying drawings, forming a part of this specification, inwhich Figure 1 is a side elevation, partly in section, illustrating oneof the clamping plates, rail bond and filling blocks in position. Fig. 2is an end elevation of myimproved railbond showing the rail in section.Fig. 3 is an inside elevation of one of the clamping plates. Fig. 4 is-acentral vertical section of the same. Fig. 5 illustrates the side andend faces of one of the filling blocks. Fig. 6 represents the top, sideand bottom elevations of -the rail bond.

A A re resent clam in lates, bein i 7 p l b p counterparts of eachother, and each is provided with the flange 1, having an inclinedsurface adapted to rest upon the inclined surface of the base of therail, whereby the,

base of the rails forms a wedge when the two plates A, A, are clampedtogether having a tendency to raise the plates and effect a clampingaction against the bottom of the rail.

2 represents flanges projecting from the side plates, provided with acurved surface I), forming a seat for the filling blocks 3, said fillingblocks 3 being each provided with a curvedsurface e of the same radiusas the radius of the curved surface 5, to maintain the surface 0 of thefilling blocks 3 in plane with the bottom of the rails enabling a rigidclamping of the rail bond in position irrespective of any angularposition the clamping plates A, A, may occupy in connecting twoadjoining rails. This feature is essential when bonding rails where twoadjoining rails are of different size or height, as is frequently thecase of connecting a new rail with an old one. Again, by seating thefilling blocks upon the curved surface of the clamping plates, the bondis not disturbed by any vibratory action of the rails caused by thesagging of the ties while a car is passing over the rails. The flanges 2of the side plate terminate at a a slight distance below the flanges 1forming an opening between which the base of the rails lie and leavessufficient clearance to permit vertical movement of the side plates asthey are-being clamped together. X 4Arepresents bolts for clamping theplates r 5 represents a bond provided with the central U-shapedprojection 6 allowing for contraction and expansion of the rails whenthe bond is clamped in position. The surface f of the bond lies of therail and the surface 9 contacts with the filling blocks 8. I

It is obvious that the filling blocks 3 may be made of one piece ofmetal notched out at its top surface to receive the projection 6 of thebond 5.

With my improved clamp a rail bond can be easily and quickly applied, atthe same time serving as a fish plate for holding the rails together.

Having described my invention, I claim:

1. The combination with a pair of adjoining railway rails, of a pair ofplates supported upon the base of said rails, filling blocks supportedby said plates, a bond lying between the under surface of said rail baseand filling blocks, and means for clamping said plates laterally belowthe rails, substantially as described.

2. The combination with a pair of adjoining railway rails, of a pair ofplates provided with an inclined flange extension ada ted to seat uponthe inclined surface of the base of the rail, a bond contacting with thelower against the bottom surface railway surface of the base of saidrails, means carried by said plates for clamping said bond in position,means for laterally clamping said plates below the rails, whereby saidbond clamping means is moved to a clamping position, substantially asdescribed.

3. The combination with a pair of adjoining railway rails, a pair ofclamping plates adapted to seat upon the upper inclined surface of thebase of the rail, a bond for bond ing said rails, means carried by saidclamping plates for clamping said bond in position against the rails,the clamping action against the bond being produced by means forlaterally clamping said plates below the rails, causing a verticalaction due to the coacting inclined surfaces, substantially asdescribed.

4. In combination with a pair of adjoining rails of a pair of platessupported upon the base of said rails, provided with a flangedprojection, said flange having a curved bearing surface, filling blockspro= vided with a curved surface ada ted to seat upon said flanges, abond lying etween the base of the rails and filling blocks, means forlaterally clamping said plates, whereby a vertical clamping action iseflected between filling blocks and rails, substantially as described.

5. A clamp for clamping adjoining railway rails, comprising a pair ofplates supported upon the inclined surface of the base of the rails,means carried by said plates adapted to contact with the base of therails, clamping means for clamping said plates laterally below the-railswhereby a wedge-like action is produced between the base of the railsand clamping plates, substantially as described.
